Attempting to repair noises in front of tub( Nor rear Shim as I can tell ). Very light loads no noise. Heavy loads , squeaking noises front tub. Will tub be damaged or minor cleaning up rough edges to. Not used extensively after squeak started ( Maybe 2 W.K.S.) After looking at your parts picture part # 313, 316, & part 312-set are the needed? Serial # is :GL732118A. Hopefully this gives you the info to make decisions. Psycho S.G. Why get frustrated as, it never helps, Thanks
